An insight into the mechanistic role of (-)-Ampelopsin F from Vatica chinensis L. in inducing insulin secretion in pancreatic beta cells.

Resveratrol oligomers, ranging from dimers to octamers, are formed through regioselective synthesis involving the phenoxy radical coupling of resveratrol building blocks, exhibiting remarkable therapeutic potential, including antidiabetic properties. In this study, we elucidate the mechanistic insights into the insulin secretion potential of a resveratrol dimer, (-)-Ampelopsin F (AmF), isolated from the acetone extract of Vatica chinensis L. stem bark in Pancreatic Beta-TC-6 cell lines.

Metabolomic analysis for disclosing nutritional and therapeutic prospective of traditional rice cultivars of Cauvery deltaic region, India.

Traditional rice is gaining popularity worldwide due to its high nutritional and pharmaceutical value, as well as its high resistance to abiotic and biotic stresses. This has attracted significant attention from breeders, nutritionists, and plant protection scientists in recent years. Hence, it is critical to investigate the grain metabolome to reveal germination and nutritional importance.

Long-standing undiagnosed foreign body aspiration with concomitant pulmonary tuberculosis in an Immunocompetent man.

Foreign body aspiration is a rare clinical finding in adults, among which very few are reported, probably due to absence of classical clinical features in adults when compared to children and due to lack of awareness. We present a 57-year-old with chronic productive cough who was diagnosed to have pulmonary tuberculosis (TB), complicated by long-standing foreign body in the tracheobronchial tree. There are many cases reported in literature where there have been misdiagnosis with respect to pulmonary TB as foreign body or foreign bodies as pulmonary TB.

Discovery, synthesis and approach of pyrrolo [3,4-]pyrroles as SARS-CoV-2 m inhibitors.

A new coronavirus has been identified as the contributing agent of the severe acute respiratory syndrome (SARS). The main viral protease (M), which controls the activities of the coronavirus replication complex, which is an essential target for the treatment of coronavirus disease. With the primary objective of targeting this receptor, we designed a new series of pyrrolo [3,2-] pyrroles, synthesized and characterized using various analytical techniques including FT-IR, UV-Vis and NMR spectroscopic studies.

A novel aureothin diepoxide derivative from Streptomyces sp. NIIST-D31 strain.

A novel vicinal diepoxide of alloaureothin was isolated from Streptomyces sp. NIIST-D31 strain along with three carboxamides, p-aminobenzoic acid and 1,6-dimethoxyphenazine. Exhaustive 2D NMR analysis and analysis of experimental, theoretical CD spectra aided in establishing the structure of compound 1.
